MUSIC--ROLL FOR MECHANICAL MUSICAL INSTRUMENTS.

SPECIFICATION forming part of Letters Patent No. 777,956, dated December 20, 1904.

Application filed July l5, 1904:- Serial No. 216,710.

Tn /LZZ whom, if may cm2/cern:

Be it known that I, GEORGE B. KELLY, a citi- Zen of the United States, residing at Jamaica Plain, Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Music-Rolls for Mechanical Musical Instruments, of which the following is a specification.

My invention relates to improvements in music-rolls for mechanical musical instruments; and it has for its object to provide a music-roll of novel and economical construction.

Heretofore the provision of music-rolls for mechanical musical instruments has been a material item of expense by reason of the cost of construction and shipment thereof, which shipmentv has usually been by mail.

By my invention a music-roll of equal or superior efficiency and adaptability'and of reduced cost of manufacture is provided.

My invention also has for its object to provide a roll adapted to receive perforated sheets of music-paper' having an end flange of novel construction arranged to be adjusted to different positions on the music-roll into coperative relation to sheets of different widths.

The invention consists in a music-roll as hereinafter described and in such music-roll in combination with means for incorporating the same into the mechanism of a mechanical musical instrument.

That which is regarded as new will be set forth in the following clauses of claim.

In the accompanying drawings, illustrating my invention, Figure l is a longitudinal sectional View of a music-roll; Fig. 2, an end view thereof; Fig. 3, an elevation of the music-roll shaft; Fig. 4, an elevation of the music-roll confining or positioning disk.

In the said drawings the reference-numeral l designates generally a music-roll which is constructed of a hollow tube 2, made of paper, pasteboard, or like similar, economical, and light material upon which the sheet of perforated music is to be Wound.

The numerals 3 3 designate the end lflanges of the music-roll, constructed of disks of paper, pasteboard, or like light and economical material the centers of which are punched out or otherwise suitably shaped to provide hubs 1i, which hubs are inserted into the open ends of the tube 2 and cemented in position therein.

The end ange Suis provided with means for connection with the hereinafter-referred-to music-roll shaft, whereby said music-roll will be caused to rotate in unison with said shaft. The means shown consist of recesses or sockets 5, formed in the said end flange, adjacent to the center portion thereof.

The reference numeral 6 designates the music-roll shaft. It is designed that this shaft shall form a permanent part of the general equipment of the mechanical musical instrument, and it is fashioned and constructed to receive and rotate the music-roll. This Shaft is provided at one end with a collar 7, adapt-v ed to serve as an abutment for the music-roll when the latter is arranged upon the shaft and to determine the position of said roll upon said shaft. The shaft is provided also at its end contiguous the collar with a clutch device 8 of known construction adapted to engage with mechanism for driving the shaft and musicroll carried thereby. The shaft has means for engagement with the connection means of the music-roll, whereby said roll is clutched to the shaft to rotate in unison therewith. This means consists of a pin 9, located adjacent the collar 7 and adapted when the music-roll is arranged upon the shaft to enter the sockets 5, formed in the end flange 3 of said musicroll. The music-roll is confined upon the shaft by means of a disk 10. This disk, as illustrated, is slitted from its periphery inward to the shaft bore or opening` thereof and is also provided with a hublOl, laterally projecting therefrom, which hub is likewise slitted, as indicated by the reference-numeral l1. The said disk l0 hugs the shaft yieldingly, yet with suiieient friction or tension to maintain its position thereon under normal conditions. The said disk is fitted to slide upon the shaft longitudinally of the latter, so that it may be freely adjusted thereupon, whereby it may be brought into cooperative relation to music-sheets of different widths that may be arranged upon said shaft, whether said sheets are carried upon the peculiar' musicroll shown in Fig. l or otherwise mounted upon said shaft, and it will be obvious that within the scope of this feature of my invention the shaft itself may constitute the roll, mandrel, or barrel upon which the sheet of music is to be wound. rlhis slitted or split disk or flange has the advantage of hugging the shaft, mandrel, or barrel with sufhcient closeness to maintain its adjusted position by frictional engagement. At the same time by reason of its slitted construction it may yield to compensate for swelling or shrinking', due to climatic conditions, of the shaft, mandrel, or barrel upon which it is arranged. T he slitting of the disk also facilitates its arrangement upon and withdrawal from the shaft. rlhe shaft is provided with a trunnion l2, as shown, adapted to journal in a suitable part of the mechanical-musical-instrument structure in a manner well known to those skilled in the art, whereby the said shaft and the music-roll arranged thereon are properly supported for rotation.

In use the music-sheet is wound upon the music-roll, (shown in Fig. 1,) which being of simple construction, inexpensive material,and of light weight materially reduces the expense incident to furnishing music-rolls for mechanical musical instruments.

To incorporate the music-roll into a mechanical musical instrument for cooperation therewith, the confining-disk l() is removed from the shaft 6, as shown in dotted lines in Fig. 3, and the music-roll is slid upon the shaft until the end flange 3 thereof abuts the collar of said flange and thc pin 9 enters into the sockets 5 of said shaft. The confiningdisk l0 is then arranged upon the shaft in close contact with the flange 3 of the musicroll, thus positioning and confining the musicroll upon the shaft in proper cooperative relation to said shaft and the other elements of the mechanical musical instrument.

By my invention is provided a music-roll of novel construction and attended by the advantage of economy in the furnishing' of music-rolls for mechanical musical instruments, combined with a music-roll shaft of novel construction and adapted to receive and cooperate with the music-roll.

Having thus described my invention, what I claim isl. rlhe herein-described music-roll consisting of a tube hollow throughout, provided with end flanges having hubs arranged and secured in the open ends thereof, one of said flanges being provided with means for connection with rotating mechanism.

2. The herein-described music-roll consisting of a tube hollow throughout and end flanges provided with hubs arranged and secured in the open ends thereof, one of said flanges being provided with sockets for connection with rotating mechanism.

3. The combinaton with a music-roll consisting of a tube hollow throughout and a music-roll shaft adapted to be passed through the tube of the music-roll and provided at one end with a collar, a clutch device for connec-' tion with mechanism for rotating said shaft and music-roll, a music-roll-confining disk arranged upon the opposite end of said shaft, and means for connecting said music-roll and shaft together for rotation in unison.

4. The combination with a music-roll consisting of a tube hollow throughout and end flanges connected thereto, one of said flanges being socketed, and a music-roll shaft provided with a collar and a clutch device at one end and with means to engage the socketed flange of the music-roll, and a music-roll-conlining disk adapted to be arranged upon the other end of the music-roll shaft to confine the music-roll thereon, substantially as described.

5. The combination with a music-roll consisting of a tube hollow throughout and end flanges having hubs inserted and secured in the open ends of the tube, one of said flanges being socketed, a music-roll shaft provided at one end with a collar, and a clutch device for connection with rotating mechanism and a pin for engagement with the socketed end flange of the music-roll, and a music-roll-confining disk provided with a slitted hub adapted to be arranged upon the opposite end of said shaft to confine the music-roll thereon, substantially as described.

6. A roll for receiving sheets of perforated music-paper, provided with a slitted end disk or flange fitted thereon and slidable longitudinally thereof, whereby it may be adjusted to different positions thereon.

7 A roll for receiving perforated sheets of music-paper, provided with an end disk or flange having a lateral ly-eXtending slitted hub, said disk or flange being adjustable to different positions on said roll.

8. A roll for receiving perforated sheets of music-paper provided with a slitted end disk or ange having a laterally-extending slitted hub, said disk or flange being adjustable to different positions on said roll, substantially as described.

In testimony whereof l have hereunto set my hand in vpresence of two subscribing witnesses.

GEORGE B. KELLY.
